and the ENTER keys until the desired display item is found.
At any time, the user can move back a mode level by pressing
the ESCAPE key. Once an item has been selected the display
will flash showing the item, followed by the item value and
then followed by the item units (if any).
Items in the Configuration and Service Test modes are
password protected. The display will flash PASS and WORD
when required. Use the ENTER and arrow keys to enter the
four digits of the password. The default password is 1111.
Pressing the ESCAPE and ENTER keys simultaneously
will scroll an expanded text description across the display indicating
the full meaning of each display point. Pressing the
ESCAPE and ENTER keys when the display is blank will
return the display to its default menu of rotating AUTO VIEW
display items. In addition, the password will need to be entered
again before changes can be made.
Changing item values or testing outputs is accomplished in
the same manner. Locate and display the desired item. If the
display is in rotating auto-view, press the ENTER key to stop
the display at the desired item. Press the ENTER key again so
that the item value flashes. Use the arrow keys to change the
value or state of an item and press the ENTER key to accept
it. Press the ESCAPE key and the item, value or units display
will resume. Repeat the process as required for other items.
If the user needs to force a variable, follow the same process
as when editing a configuration parameter. When using the
Navigator display, a forced variable will be displayed with a
blinking “f” following its value. For example, if supply fan requested
(FAN.F) is forced, the display shows “YESf”, where
the “f” is blinking to signify a force on the point. Remove the
force by selecting the point that is forced with the
ENTER
key and then pressing the arrow keys simultaneously.
When using the scrolling marquee display, a forced variable
is displayed by a blinking “.” following its value.
Depending on the unit model, factory-installed options and
field-installed accessories, some of the items in the various
mode categories may not apply.
System Pilot Interface — The System Pilot interface
(33PILOT-01) is a component of the 3V system and can
serve as a user-interface and configuration tool for all Carrier
communicating devices. The System Pilot interface can be
used to install and commission a 3V zoning system, linkage
compatible air source, universal controller, and all other devices
operating on the Carrier communicating network.
Additionally, the System Pilot interface can serve as a wallmounted
temperature sensor for space temperature measurement.
The occupant can use the System Pilot interface to
change set points. A security feature is provided to limit access
of features for unauthorized users. See Fig. 3 for System Pilot
interface details.
CCN Tables and Display — In addition to the unitmounted
scrolling marquee display, the user can also access the
same information through the CCN tables by using the System
Pilot, Service Tool or other CCN programs. Details on the
CCN tables are summarized in Appendix B. The point names
used for the CCN tables and the scrolling marquee tables may
5
be different and more items are displayed in the CCN tables.
As a reference, the CCN point names are included in the scrolling
marquee tables and the scrolling marquee acronyms are included
in the CCN tables in Appendix B.
GENERIC STATUS DISPLAY TABLE — The GENERICS
points table allows the service/installer the ability to create a
custom table in which up to 20 points from the 5 CCN
categories (Status, Config/Service-Config, Set Point, Maintenance,
and Occupancy) may be collected and displayed.
In the Service-Config table section, there is a table named
“generics.” This table contains placeholders for up to 20 CCN
point names and allows the user to decide which points are displayed
in the GENERIC points table. Each one of these placeholders
allows the input of an 8-character ASCII string.
Using a CCN method of interface, go into the Edit mode for
the Service-Config table “generics” and enter the CCN name for
each point to be displayed in the custom points table in the order
they will be displayed. When done entering point names, download
the table to the rooftop unit control.
IMPORTANT: The computer system software
(ComfortVIEW, Service Tool, etc.) that is used to
interact with CCN controls always saves a template of
items it considers as static (e.g., limits, units, forcibility,
24-character text strings, and point names) after
the software uploads the tables from a control. Thereafter,
the software is only concerned with run time
data like value and hardware/force status. With this in
mind, it is important that anytime a change is made to
the Service-Config table “generics” (which in turn
changes the points contained in the GENERIC point
table), that a complete new upload be performed. This
requires that any previous table database be
completely removed first. Failure to do this will not
allow the user to display the new points that have been
created and the software will have a different table
database than the unit control.
